Statutory nuisance and why a condition is not a substitute

A planning condition and a statutory nuisance are two different things, enforced by two different teams under two different Acts, and neither one does the other's job. A condition limits what the permission allows. A statutory nuisance under Part III of the Environmental Protection Act 1990 bites on what is actually happening, whether or not planning permission was granted for it. If the extract fan next door is keeping you awake, the question is which of the two routes fits your facts, and the answer is often both.

Planning permission has never been a defence to a nuisance claim.

The two regimes and who runs them

Statutory nuisance sits with environmental health. Section 79 of the 1990 Act lists the categories: noise emitted from premises so as to be prejudicial to health or a nuisance, smoke, fumes or gases, dust, steam, smell or other effluvia from industrial, trade or business premises, accumulations and deposits, artificial light, and insects. The test has two limbs, prejudicial to health or a nuisance, and the second is the one most complaints rely on.

Planning conditions sit with planning enforcement. A condition is only lawful if it is necessary, relevant to planning, relevant to the development, enforceable, precise and reasonable in all other respects. It attaches to the permission and controls the development that permission authorises, nothing wider.

The practical difference shows up fastest in what each team asks you for. Environmental health wants a pattern of occurrence and its effect on you. Planning enforcement wants the condition number and evidence that it was breached on a stated date.

Where entertainment noise is involved a third regime joins in, because licensing conditions operate separately again. The overlap is set out in planning control and licensing control of venue noise.

What an abatement notice can require

Where a local authority is satisfied that a statutory nuisance exists, or is likely to occur or recur, section 80 says it shall serve an abatement notice. The duty is not discretionary once the authority is satisfied, which is why a well-evidenced complaint is worth more than a persistent one.

The notice can do three things. Require the nuisance to be abated or prohibit or restrict its occurrence or recurrence. Require specified works or steps. And specify the time within which that has to happen.

Recipients have 21 days to appeal to the magistrates' court. Contravening the notice without reasonable excuse is an offence, punishable by a fine, with a higher maximum where the nuisance arises in the course of a trade or business.

Section 82 gives you a direct route. An individual aggrieved by a statutory nuisance can bring proceedings in the magistrates' court without the council. You have to give the person responsible written notice of your intention first, three days for noise and 21 days for other categories, and you have to be able to prove the nuisance. It is a real remedy and it is used, mostly where a council has gone quiet.

Why permission is not a defence

This is the point most often misunderstood by both sides.

A planning permission authorises development. It does not authorise a nuisance. The Supreme Court confirmed the position for private nuisance in Coventry v Lawrence (2014), holding that the grant of planning permission does not of itself provide a defence, although the implemented permission may be relevant to the character of the locality against which the nuisance is judged. Statutory authority as a defence requires an Act of Parliament, not a development consent.

The consequence for an operator is uncomfortable. A takeaway can hold permission for an extract system, install exactly what was approved, comply with every condition, and still be served with an abatement notice because the smell is a nuisance in fact.

The consequence for a complainant is more hopeful than most people expect. "The council gave them permission" is not the end of the conversation. It is the start of a different one, with a different team, under a different statute.

What permission does affect is the baseline. Where the character of an area has lawfully changed because a permitted development has been implemented, the standard against which nuisance is measured changes with it.

Best practicable means

The main defence to an abatement notice for noise, dust, smell and similar nuisances on industrial, trade or business premises is that best practicable means were used to prevent or counteract the nuisance.

Section 79(9) defines it: reasonably practicable having regard to local conditions and circumstances, the current state of technical knowledge, and the financial implications. Practicable means something a reasonable operator in that trade could do, not something theoretically possible at any cost.

In an extract case, best practicable means usually comes down to a documented maintenance regime for the filters, a discharge point at the right height and direction, an attenuator on the fan, carbon filtration where grease filtration alone is insufficient, and a log showing all of it was done. An operator with a signed service record every three months is in a very different position from one with no records at all.

Which means the defence rewards paperwork, and that cuts both ways for a complainant. If the operator can produce the log, the notice may fall. If they cannot, it will not.

Complaining to the right team

Six steps, in order, and the order matters.

1. Identify which regime fits. If the activity is doing something the permission never allowed, or breaching a stated condition, that is planning enforcement. If it is a lawful activity causing a nuisance in fact, that is environmental health. Many cases are both, and you can report both.
2. Find the permission. Search the authority's online register by address, open the decision notice and read the conditions. Hours of operation, plant noise limits, extract specifications and delivery times are the ones most often breached.
3. Report in writing, with a reference to the condition number where there is one.
4. Ask for a case reference and the name of the officer.
5. Keep a log from day one. Not a summary written later.
6. Ask, in writing, which legal test the authority is applying and what evidence it needs from you. That question changes the quality of the response more than any amount of chasing.

Where the authority proposes monitoring, ask how long for and where the equipment will sit, because an unattended monitor in the wrong position produces data that proves nothing. The practical limits are set out in unattended noise monitoring: duration, position, validity.

Where a breach of condition notice is faster

A breach of condition notice under section 187A of the Town and Country Planning Act 1990 has one powerful feature: there is no right of appeal to the Planning Inspectorate. The recipient either complies within the stated period, which must be at least 28 days, or commits an offence. Challenge is limited to judicial review.

Compare that with an enforcement notice under section 172, which carries a full appeal to the Inspectorate and can take a year or more to resolve. Or with a nuisance case, which requires the authority to be satisfied a nuisance exists and then survives a magistrates' court appeal.

So where a condition is clear, numerical and plainly breached, a breach of condition notice is usually the quickest route to a change in behaviour. "No deliveries before 07:00" is enforceable. "Noise from the premises shall not cause nuisance to nearby residents" is not, because it is imprecise and simply re-states the nuisance test.

That is the structural weakness in relying on conditions. A condition tight enough to enforce has to be numerical and measurable, and measuring it costs the council money. A condition loose enough to cover everything is unenforceable. Neither version substitutes for the nuisance regime, which asks only whether the thing complained of is a nuisance in fact.

Enforcement time limits were extended by the Levelling-up and Regeneration Act 2023, so check the current position before assuming a long-standing breach is immune.

The evidence to keep

A nuisance case is won on records, and almost nobody keeps good enough ones.

Keep a dated log with the start and finish time of each occurrence, the duration, what you could hear or smell, which room you were in, whether windows were open, and what you were prevented from doing. Sleep disturbance with times is the most persuasive single entry.

Note the weather, because wind direction decides most odour cases and some noise ones.

Photograph the source where it is visible, including the discharge point and its height relative to your windows. Keep every piece of correspondence, including the dates you reported and the replies.

Do not record audio inside a neighbour's property and do not install anything on their building. A log in your own handwriting, consistent and dated, carries more weight in a magistrates' court than a phone recording with no calibration.

Where the problem is a proposal rather than an existing use, the point to engage is before permission is granted. A Noise Impact Assessment or an Odour Assessment submitted with the application is the document to read and comment on, because conditions are drafted from it.
